When using states = 'ENTIRE', inMemory = FALSE, estimates fail
lwrogers-uw opened this issue · comments
After acquiring data and loading it for the entire USA, estimates fail including volume, biomass, etc.:
Get the entire USA
usa <- getFIA(states = 'ENTIRE', dir=dataDir, load = FALSE)
Load previously downloaded FIA data
usa <- readFIA(dir=dataDir, inMemory = FALSE, states = 'ENTIRE')
Get the volume over time
volume(usa)
fails:
Error in readFIA(dir = db$dir, common = db$common, tables = reqTables, :
Data unavailable for: ENTIRE . States not found in specified directory.
Sorry for the late response here.
We worked this out previously, but for completeness, the issue arises from specifying inMemory = FALSE in the call to readFIA when attempting to read ENTIRE. Our larger-than-RAM methods are designed to work with combinations of state subsets, and as ENTIRE is simply a merged version of all state subsets (e.g., TREE table is merged into a single csv), we can't use inMemory=TRUE.
I've added a more informative warning to readFIA that will explain the above - great catch!
